| 摘 要： | 果品损伤与外界冲击激励的关系是科学控制果品冲击损伤的一个必要条件。采用Kuwabara-Kono模型描述果品的黏弹性,并在此基础上建立了多层果品的动力学模型,研究了半正弦脉冲激励下的多层果品冲击动力学特性,得到了果品典型冲击损伤特征参数随脉冲激励变化的规律。结果表明：果品特征参数、脉冲激励幅值、层数等对各层果品加速度响应峰值、达到峰值的时间等损伤指标影响显著。

| Abstract: | It＇s very important to investigate the inner relationship between fruit damage and shock,considering fruits are usually stacked during transportation.The mechanical model of multi-layer fruits is built and the shock response of each layer under the action of half-sine acceleration pulse is investigated.It shows that the effect of viscoelastic parameter of fruits,pulse peak and numbers of layers on the typical bruising parameters of fruits is noticeable. |
| |
| Keywords: | half-sine acceleration pulse fruits shock stacks |
